1.1. Features of the DiMAX Navigator 

1.1.1. Form and Functions 

Massoth Electronics defines a new standard with the ergonomically shaped DiMAX Navigator. The handheld 

cab is designed to facilitate right handed and left handed operation. The large backlit display provides detailed 

information for locomotives, switches and other devices on the model railway. 

The DiMAX Navigator offers the unique capability of allowing the user to execute two separate functions concurrently, 

e.g. controlling a locomotive while operating turnouts. In additional to controlling turnouts, the second 

function can be used to control switch routes or control a second locomotive. 

1.1.2. Navigator Compatibility with Other Digital Central Stations 

The DiMAX Navigator is designed to operate with all Massoth DiMAX bus compatible central stations, e.g., Di- 

MAX 800Z, DiMAX1200Z , DiMAX 1210Z, and LGB ® MTS III. The DiMAX Navigator may also be used in conjunction 

with central stations operating the XpressNet© or LocoNet© bus protocols, e.g., Lenz ® , UHLENB- 

ROCK ® , ROCO ® , FLEISCHMANN ® , and PIKO ® . 

1.1.3. Navigator Function Limitations with the LGB® 55006 MTS III Central Station 

The LGB ® 55006 MTS III Central Station operates a simplified version of the DiMAX operating system. When 

combined with the Massoth Navigator, the MTS III central station offers enhanced operations. However, to 

operate the full range of features discussed in this manual, the Navigator must be operated in tandem with a 

Massoth central station. 

When operating the Massoth Navigator with the LGB ® 55006 MTS III central station, please note the following: 

• Only speed steps 14 and 28 available. MTS III is limited to 14 speed steps without the Navigator. 

(Note: Loco decoders must be programmed for the correct speed step setting (see CV#29) to enable 

reception of 28 speed step commands.) 

• MTS III does not offer an isolated programming track, therefore 

o Only short address (CV #1) programming is available. 

o The Navigator cannot read CV values or write CVs (other than CV#1) 

o 

(Note: since Software Version 1.5 you can write CVs!) 

Operations Mode Programming (a.k.a. Programming-on-the-Main or PoM) and Register Mode 

programming not available. 

• No automatic function routines are available. 

• Wireless operation requires the Massoth RF Receiver – Item #8132001. The Massoth Navigator operating 

frequency differs from that of the current MTS wireless devices. Also note, the Navigator wireless 

components are bi-directional; the MTS wireless components are uni-directional. 


MASSOTH 

1.1.4. Hook Up 

The DiMAX Navigator may be used in tethered (cable) mode or wireless mode. When switched ON, the DiMAX 

Navigator will log into the central station via the bus cable. When communication is unavailable via the cabled 

bus port, the Navigator will log in via wireless mode. If no connection can be established with the central station, 

an error message will be displayed. A symbol in the upper right hand corner of the Navigator display communicates 

the current connection mode. 

1.1.5. Wireless Operation (Needs software version V1.20) 

When operating in wireless mode, the Navigator’s communication remains bi-directional. As a result, the 

Navigator can send commands to and receive updated information from the central station and other bus 

components. The DiMAX Navigator radio transmission frequency differs from that of the LGB ® MTS RF 

Transmitter 55051, therefore both systems can be used concurrently without interference. 

Compared to other DCC wireless throttles, the Navigator offers superior wireless data transfer speed and the 

operational range. A range of 300 feet is typical for outdoor use, but tests have revealed performance at up to 

1000 feet. 

Range and performance can be adversely affected by certain building materials and interference with other 

wireless devices, including: computer components, Blue Tooth devices, electronic garage door openers, and 

wireless headsets. In extreme circumstances, such environmental factors may render wireless operation 

impossible. 

When operating the wireless Navigator in the presence of radio frequency interference, changing the channel 

may improve performance. (See 5.5.2.1. in this manual) 

If multiple RC Navigators are used every Navigator needs to be set to a seperate ID.

MASSOTH 

1.2.2. DISPLAY A 

The easy-to-read display offers detailed information regarding the status of the current driving locomotive and 

other devices on the model railway. The following information is communicated via the Navigator display 

interface: loco icon, loco address, selected number of driving speed steps, selected protocol for function 

commands (NMRA parallel or MTS serial), status for functions F1 - F16, driving direction, driving speed (shown 

as integer speed step value and as a bar graph), and more. 

Measuring 2-1/8” x 1-1/32” (54mm x 26mm), the backlit display provides ideal visibility in darkened rooms. The 

back light may also be switched off to extend battery life during wireless operation. 

This is the general display arrangement: 

The status bar: 

The main function array: 

The auxiliary function array shows the following indications after start: 

The menu bar shows the current assignment of the three menu keys: M1 , M2 , M3 . 


MASSOTH 

1.2.3. Menu Keys M 

The menu keys M1 , M2 , M3 are assigned different functions depending on the current menu selection. The 

current key functions are shown in the black background menu bar at the bottom of the display, e.g.: 

1.2.4. Stop Keys B + C 

The DiMAX Navigator features two programmable stop keys. The stop keys work independently of each other, 

allowing each key to be programmed to perform a different stop function. For example, one key can be 

programmed to trigger an Emergency Stop, removing power from the track while the second key can be 

programmed to send a ‘Broadcast Packet Stop’ command, bringing all locomotives safely to a halt without 

removing power from the rails. The function assignment of the stop keys is programmable for each DiMAX 

Navigator, allowing multiple Navigator users on the same layout to each customize their handheld. (See 5.4.2. 

of this manual for programming information.) With the factory default setting, the right hand stop key B 

initiates an Emergency Stop and the left hand stop key C cancels the emergency stop. 

1.2.5. Controlling the Primary Function D 

The primary function of the DiMAX Navigator is controlled by the transparent dial knob D . The dial knob 

controls direction and speed of a locomotive or a locomotive consist. The zero point of the dial knob is 

highlighted by a red background spotlight. In addition, the dial knob may be backlit in a similar fashion to the 

display. Individual programming of these features is accomplished in the Navigator’s configuration menu. 

1.2.6. Controlling the Secondary Function E 

The secondary control function of the DiMAX Navigator is accomplished with the three keys beneath the round 

dial knob D . The secondary function can control a second locomotive or control switches, switch routes or signals. 

The primary and secondary function controls can be operated simultaneously, making the DiMAX Navigator 

uniquely suited to the complex operations of model railways. 


MASSOTH 

1.2.7. Keyboard G 

The keyboard of the DiMAX Navigator can be used to trigger up to sixteen functions (F1 – F16). The F-Key F 

shifts control between the first and second function level (first function level = function 1 to function 8, second 

function level = function 9 to function 16). On each key, second function level values are printed as subscripts 

to the first function level values. 

1.2.8. Light Function H 

The light key H controls the locomotive headlights. The light function, F0, is an additional function to the previously 

discussed functions, F1-F16. 

1.2.9. Loco Selection Key I or M2 

Pressing the Loco Selection Key I or M2 leads to the locomotive selection menu of the DiMAX Navigator. 

There are several methods of selecting a locomotive. For more detailed information, please see section 3.1.7. 

1.2.10. Function Level / On/Off F 

The F key F defines the function level for the numbered keys 1-8. The current setting is indicated below the locomotive 

name on the Navigator display. The first level is displayed as F1...8 . Accordingly, the second level is 

displayed F9..16 . Pressing the F-key F toggles control between the first level, 

F1...8 and the second level F9..16 (You can switch the keyboard from the secondary function back to the 

primary function by pressing key F again.) 

When operating the DiMAX Navigator in wireless mode, press the F-key F to turn the Navigator ON. To shutdown 

the Navigator, press and hold the F-key F . 

2. Starting the Operation 

2.1. Switching ON/OFF (Needs software version V1.30) 

• During tethered operation the Navigator starts automatically 

• In wireless operation the Navigator must be switched ON with the F-key F 

• Depressing the F-key F for more than one second switches OFF the Navigator. 

2.2. Selecting the Loco Address (Needs software version V1.30) 

After pressing the locomotive selection key I or M2 the DiMAX Navigator displays the locomotive selection 

window. Enter the loco address via the keypad, for example, loco address 0003 After confirming the address 

by pressing M3 , the loco is ready for driving operation and the DiMAX Navigator automatically returns to the 

driving mode screen. Default locomotive addresses are typically listed in the locomotive manual or the decoder 

manual. For most NMRA DCC decoders, the default address is 3. 


MASSOTH 

2.3. The First Test Run 

Congratulations! After entering the loco address and pressing M3 to confirm, the loco is ready to be controlled 

with the transparent dial knob. With the Navigator factory default settings, the locomotive will be controlled with 

28 speed steps and parallel data processing. More detailed properties like loco icon, loco name, etc., will be 

defined in Loco Configuration. (Please see section 3.) 

Please note that lights of locomotives configured for 14 speed steps (see locomotive decoder CV#29) will not 

display correctly if the locomotives are controlled with 28 speed steps. The same is true for locomotives configured 

for 28 speed steps that are controlled with 14 speed steps. In these cases, the lights of the locomotives 

may flicker on/off with each advancing speed step or the lights may not work at all. 

3. Loco Configuration 

3.1. Access to Loco Configuration Menu (Needs software version V1.30) 

The loco configuration menu is used to define the attributes of a locomotive, for example, configured speed 

steps, selected protocol for function commands, or the locomotive icon. To enter the loco configuration 

menu, press and hold the M2 key for about 2 seconds. 

3.1.1. Delete Locomotives (Needs software version V1.30) 

The first displayed window of the loco configuration menu allows configured locomotives to be deleted. To delete 

the locomotive currently displayed, press the M1 key. 

3.1.2. Speed Step Configuration (Motorola operation from software version V1.40) 

Upon selecting the loco configuration menu, the first window is used to select speed step configuration. Toggle 

between 14D , 28D , 128D and 14M speed steps by pressing the M2 key. D stands for NMRA DCC operation; 

M stands for Motorola operation. Confirm the selection with the M3 

key. After pressing the “OK” key, M3 , the next window is automatically displayed. 

Please note, MTS III only allows 14D and 28D speed step operation. 

3.1.3. Protocol for Function Commands – NMRA Parallel/MTS Serial Selection 

Toggle between the NMRA Parallel (“P”) and MTS Serial (“S”) function command protocols by pressing key M2. 

Confirm the selection by pressing the M3 key only if wishing to avoid configuration of the F-keys (see 3.1.4. 

in this manual). Please check the decoder or locomotive manual to determine the appropriate protocol for function 

commands. 


MASSOTH 

Notes: 

LGB ® onboard decoders, featuring the silver/black ‘Analog and Digital’ 

sticker may be controlled with NMRA Parallel commands. 

LGB ® locomotives equipped with a Decoder Interface or a Direct Decoder 

Interface and fitted with an LGB ® 55021 decoder are controlled by MTS 

Serial commands. (Unless the 55021 decoder and locomotive circuit board 

have received a Massoth “P” upgrade.) 

LGB ® locomotives equipped with a DCC Interface may be controlled with 

NMRA Parallel commands. 

3.1.4. F-Key Configuration (Needs software version V1.40) 

The momentary operation operates the F function like a toggle switch; hitting the key once switches the function 

on. The second push switches the function off, e.g. lights, smoke generator etc. 

The continuous operation keeps the function activated as long as the key is pressed. 

The F-key configuration window shows you the selection of your operation (momentary or continuous) e.g.: 

when the function key # 8 is highlighted, the continuous mode is selected for the F8 function. When the 

function key # 8 is on normal background: the standard or momentary mode is selected for the F8 function. 

In the momentary operation e.g. the whistle will be triggered by hitting the respective F-key once and brief 

without any further influence to the triggered whistle. 

However, in continuous operation the whistle is active as long as the F-key is pressed. Releasing the F-key 

ends the whistle. 

Confirm your selection with the M3 key. 

This F-key operation works with sound, light, smoke, or any other special function. Full use of the continuous 

operation function with sound can only be assured with sound units supporting this feature. The eMOTION XLS 

Sound Decoder and some limited brands provide this feature. 

3.1.5. Loco Icon Selection 

Use keys M1 and M2 to scroll through all loco icons available. In addition you may choose your locomotive 

icon via the number key pad to select the locomotive icon directly. (Please, see 7. Locomotive Icons in this manual.) 

Confirm your selection by pressing key M3 . 


MASSOTH 

3.1.6. Loco Name Definition 

This window will automatically open after you’ve pressed M3 in the above mentioned step. 

Now, check for the blinking cursor. Press M2 for scrolling forward through the list of characters (choices are 

shown below). Use M1 for moving backwards. 

0 1 2 3 4 5 6 7 8 9 A B C D E F G H I J 

K L M N O P Q R S T U V W X Y Z - / _ 

Select by scrolling through the characters – see choices below - with keys M1 (forward) and M2 (backward). 

Once the window shows your selected character use the right hand arrow key to move the cursor to the right 

. The previous character will be shown solid while the cursor in the new position keeps blinking during 

your next selection. Now you are ready to define the next character. You may use up to ten (10) characters for 

your locomotive name. 

Please note that a blank character is located between the “/” and the “0”. 

E.g. choose “V51” as the locomotive type or “V 51 Jack” as the locomotive V51 of your fellow model railroader 

Jack. End the definition of the loco name with the round stop key of the second loco function. To delete “Jack” 

from the locomotive name, move the cursor between “V51” and “Jack” and press the stop key . After 

selecting OK the new loco name will be stored and the correct name will be shown next time you select this 

locomotive. 

This menu allows you to define your personal favorite locomotive name which will be displayed beneath the 

loco icon from now on in the normal driving mode. Also, when utilizing the loco driving function in the secondary 

function the loco name will be shown as well. In this case the loco name is displayed beneath the loco address. 

The name of the locomotive is only stored in the Navigator. Thus a locomotive may have different names on 

different Navigators. That means: when using several Navigators at the same time, each user may define his 

personal choice name for the same locomotive. 


MASSOTH 

3.1.7. Save Configuration 

Once you have finalized the configuration of your locomotive, please save your entries. Pressing M2 will save 

your data permanently in the central station, so when the central station is switched off, your setting will be 

available the next time you switch it on. Saving with M3 will keep the data only during the duration of your 

current operation, so when the central station is switched off, your settings will NOT be available the next time 

you switch it on. 

When you start your operation the next time the last selected locomotive will show up in the driving mode. 

However this will happen ONLY if you have saved the data with M2 in the central station. 

3.1.8. Defining Additional Locos 

To define additional locos, please proceed according to chapter 3. of this manual. 

3.1.9. Loco Log On (Needs software version V1.30) 

Data of already defined locomotives are stored in the central station and the Navigator. All stored locomotives 

will be displayed in the loco selection window (see graphic below). Scroll through your stored locomotives with 

M2 and select with M3 . 

OR – in case you know the loco address of your choice locomotive you may enter that address directly via the 

key pad and confirm this with M3 . 

In case you enter an unknown address, this will be accepted as a new active address for a new locomotive 

which needs to be configured later. To exit the loco selection window without choosing a locomotive press the 

M3 key. 


MASSOTH 

3.1.10. Loco Log Off (Needs software version V1.30) 

You do not have access to a locomotive that is already selected by another user. The other user/ Navigator has 

to log off his locomotive before you are able to run this locomotive with your Navigator. Opening the loco selection 

window with M2 or 0# automatically logs off the locomotive. 

NOTE: the management of locomotives is accomplished in the digital central station. When you select one of 

the locomotives available, this locomotive will be marked as occupied and can not be selected by other users. 

This does not depend upon the operational status of the locomotive. 

A driving locomotive is always logged off “passive” because it still is receiving data from the central station. 

The locomotive is only logged off from the control bus and may be selected by other users. If you log off a locomotive 

that is not moving it is logged off “active”. This means, it is logged off in the central station and it is 

not listed as active anymore. This can be checked easily in the display of the central station as the number of 

the active locomotives is always displayed in the upper right corner of the display. 

3.1.11. Re-Gaining Control After Switching Locos 

Example: You are running loco # 1. Then you want to run loco # 2. So, you select loco # 2 on the Navigator as 

loco #1 is still running and you drive loco #2. Now, you do not have direct access to loco #1 anymore. Loco #1 

is logged off “passive”. 

To return to loco #1 you have to select loco #1, again. Initially, the position of the speed dial knob will not match 

the current speed and driving direction of loco #1. This needs to be synchronized. 

As a hint the respective part of the dial where loco #1 is actually running is backlit and blinking. Turn the dial 

into this direction until the light stops blinking. This indicates that you re-gained full control of loco #1. 

3.1.12. Selecting a Logged-On Loco (Needs software version V1.10) 

You cannot get access to a locomotive that is already selected by another user (see graphic below). The other 

user/ Navigator has to log off this locomotive for you to be able to control this locomotive with your Navigator. 

Open the loco selection window with M2 or 0# and this loco will be logged off automatically, regardless if it 

is driving or not. 


MASSOTH 

3.1.13. Analog Loco 

The DiMAX Navigator does also control analog locomotives. The address of an analog loco is generally “0”. Locomotive 

properties like speed steps and functions cannot be defined for an analog locomotive. A loco configuration 

is not possible, the analog locomotive is displayed with the icon of an analog throttle. 

NOTE: The digital AC on the track may cause analog locomotives to emit a high frequent sound. In general 

this does not have an impact on the electronics of your locomotive. (Please check your manufacturer’s manual 

on this topic). 

3.2. Driving Operation 

As usual the locomotive is controlled by the transparent dial knob. With the dial knob is in the middle position 

the loco is not running and speed step 000 will be displayed. The arrow in front of the speed step indication 

symbolizes the driving direction. The zero position of the dial is marked by a red light. 

3.2.1. Additional Functions during Driving Operations 

The special functions, like smoke generator, lights, sound functions etc, are operated with the function keys 1… 

8. In case the locomotive is on parallel data transfer the respective function icon is highlighted in the display. In 

case of serial data transfer, however, the F1 function icon is blinking several times. 

The F-key toggles between function level 1 to 8 and function level 9 to 16. The functions F1 to F16 are marked 

on the function keys. (See graphic below) 

4. Secondary Function 

The DiMAX Navigator features a secondary control function for various purposes. The secondary control function 

of the DiMAX Navigator is accomplished with the three keys beneath the round dial knob D. At the same 

time and parallel to the primary function the secondary function can handle a second locomotive, switches, turnout 

routes, or signals. 


MASSOTH 

4.1. Info Mode (Needs software version V1.30) 

After start up, the DiMAX Navigator displays the info mode in the lower section of the display. This part of the 

display is also used for the secondary function. This mode shows system information of the central station e.g. 

maximum amperage, current amperage, and utilization ratio in percent. In addition, system messages are 

issued. 

You may switch to the secondary function of the DiMAX Navigator with the M1 key at any time. With the first 

M1 key stroke the key pad keys 0 to 9 is switched to the secondary function. This is indicated in the display 

beneath the locomotive name. The indication changes from F1…8 to 2.Fu. In this condition a locomotive can 

be controlled as usual with the primary controls, however, no function key triggering is possible. You may choose 

the assignment of the secondary function by pressing M1 again. Pressing the F key exits the secondary 

function and the key pad is assigned back to the primary function. 

4.2. Switching Commands 

Pressing the M1 key the second time gives you access to the turnout command mode. Enter the address of 

your switch with your keyboard of the Navigator and operate this switch with the arrow keys of the secondary 

function to the left or to the right . In addition, you may scroll with the round stop key through the last 

used switches . E.g. if you used switch #0001 and #0006 already you may return to switch #0001 

and then to switch #0006 by pressing the round stop key repeatedly. This even works when you change to the 

primary function and return to this mode by using the F key. Thus you may control a locomotive to the full extend 

and control the last 8 used switches simultaneously. 

4.3. Operating Turnout Routes 

In addition to control single switches you may operate turnout routes as well. These need to be previously defined 

as described in 5.3.1. of this manual. Hit the M1 key repeatedly until the menu switch route is displayed. 

Enter the address of your turnout route via the keyboard and operate it with the right hand arrow key . All 

elements of the turnout route receive one after the other the previously defined command. Similar to the switch 

command function you may scroll the last 8 used turnout routes with the round stop key and operate 

them. 


MASSOTH 

4.4. Second Locomotive 

Two locomotives can be controlled independently at the very same time with the DiMAX Navigator. To change 

into this mode press the M1 key repeatedly - or scroll through all stored locos using the round stop button - until 

loco: XXX is indicated. Enter the address of the loco of your choice via the keyboard and confirm your selection 

with the right hand arrow key . Please note that you can only select previously stored and configured 

locos. You cannot define a new loco in the secondary function at this time. 

After selecting a stored loco the display shows the corresponding data of this loco: loco address, loco name, 

light, functions 1…8 as well as driving direction and speed steps in use. 

You may control the second loco with the arrow keys . The round stop key resets the speed steps to “0” 

and thus stops the locomotive. During the stop you may change the driving direction by pressing the stop key 

again, e.g. to change the lights during standstill. A change of locomotive is accomplished by the “0#” key. The 

functions F1…8 of the second loco can be controlled only when the secondary function indication is active. To 

activate this secondary function use key M1 . 

5. General Settings 

General settings of the DiMAX Navigator and various layout configurations are defined in the “main menu” 

section of the Navigator. Press M3 to get from the operational window to the main menu. All menus of the 

Navigator agree to the same basics: 


MASSOTH 

• M1 = navigation (move the cursor) 

• M2 = confirm the selection 

• M3 = return to normal operation 

Select the menu of your choice with M1 and confirm this selection with M2. 

5.1. Consist Operation (Multi heading) 

Multiple locomotives can be combined in a consist to operate a train, e.g. long freight trains. Prior to using a 

consist it needs to be defined. Please see 5.3.1. of this manual. 

Note: When defining a consist it is mandatory that all locomotives are configured with the same number of 

speed steps and in parallel data processing mode. The system will not accept locomotives with different 

configurations. Please see 5.3.2. of this manual for further information. 

The consist selection window opens up showing consist #1 as default. Scroll through all previously defined consists 

with M2 . Select and confirm your choice with M3 . The keys M3 and M2 change the indication to the 

consist operation mode. The consist operation mode shows all of the addresses of the combined locos (max 

4). Controlling a consist is comparable to regular locomotive control. 

In case the selected consist contains an un-configured loco address an “X” will be displayed behind the address. 

The same indication is shown if one of the locos is presently used by somebody else. 

If so, select a different consist with M2 or exit the consist operation mode with M3 and M2 . The primary 

function of the DiMAX Navigator may be changed back to loco operation mode. The menu window then shows 


MASSOTH 

“loco control” as first choice, see graphic below. 

5.2. Decoder Programming (Needs software version V1.30) 

The DiMAX Navigator supports all programming methods in accordance with the latest NMRA/DCC standards. 

Please note that not all of the DCC systems currently available can be programmed according to this standard. 

The manufacturer of your DCC system should give you in-depth information. Choose the programming method 

applicable to your digital system. A decoder confirms every successful programming cycle with a short voltage 

spike (brief engine bucking). A motor needs to be connected to the decoder for this purpose, switch decoders 

require a switch drive. This ensures that the programming command has been received correctly and has been 

executed. 

5.2.1. Locomotive Address 

This is the menu window for brief locomotive programming. The number of addresses selectable is 1-10239. 

The DiMAX Navigator computes automatically the appropriate values for CV’s 1, 17, and 18. In addition, speed 

steps can be set to 14 or 28. 

5.2.2. CV Reading 

The read-out of a decoder’s CV settings shall not be mistaken for a programming procedure. However, it is 

essential for checking the previously programmed settings. The DiMAX Navigator supports this function. After 

selection of the decoder reading function a CV value needs to be inserted and the respective setting will be 

shown subsequently. 


MASSOTH 

5.2.3. CV Programming 

Programming (writing) the CV values is the easiest way of programming the decoder. This method is utilized by 

most of the DCC systems. Using your DiMAX Navigator the central station or the PC, you select the desired CV 

parameter and insert your desired value. Programming is done on a separate by programming track or a piece 

of track that is used as programming track, depending on the digital system. Please check the manual of your 

central station. 

5.2.4. Writing CVs Bit By Bit 

Some of the CV (e.g. CV 29, CV 49) parameters consist of multiple binary values. This means that several 

values are combined in one value. Each function has a bit and a value. Programming a CV of this kind requires 

that all values of all functions controlled by this CV need to be summed up. A deactivated function always is “0”, 

an active function must be programmed with the respective value according to the CV table. The sum 

represents the value of the CV and must be written into the CV parameter. All known programming methods 

may be used. 

Let’s look at the NMRA configuration register (CV 29) of the eMOTION XLS sound decoder for example. You 

intend to program “normal driving direction, 28 speed steps, digital and analog operation, internal driving 

curve, and a short locomotive address”. This sums up to 2+4=6 according to the CV table. So CV 29 should 

be programmed with “6”. 

5.2.5. Register Programming / Indirect CV Writing 

Register programming was the first method of CV programming. This old method is still supported in order to be 

compatible to outdated central stations and programming units. The CV value is to be entered into an 

intermediate variable. The decoder thereafter does the real programming. The input into register 5 and 6 is 

accomplished in this menu window. The CV 1 to 4 are entered directly; all other CVs with higher numbers are 

programmed indirectly (by register programming) 

Let’s assume you want to set the total volume (CV 200) of your eMOTION XLS Sound Decoder to “10”. The 

first step is to go into the register programming mode, insert “6” thereafter “200”. If this was successful the next 

step will be to program “5” to “10”. Now your volume is set to “10”. 


MASSOTH 

5.2.6. PoM Programming on Main Track 

The PoM method is the only procedure to accomplish programming on the main track. All of the CV 

programming can be done except CV 1, 17, and 18 (address) with the decoders. 

PoM programming should only be performed when the locomotive is not in motion. 

After choosing the “PoM Trackprg” menu insert the desired CV number and confirm your input with 

M2 . The curser will jump to the next line waiting for the input of the respective CV value. After confirmation 

with the M2 key programming is initiated and will be confirmed by a brief engine bucking. To return to the primary 

operation window press M3 . 

Note: In general programming is accomplished with DiMAX Digital Central Stations only on the programming 

track (exception PoM). Programming on the main track by PoM is supported. Programming has been tested 

thoroughly with these manufacturers: Massoth ® , LGB ® , Lenz ® , Zimo ® , Esu ® , Uhlenbrock ® . 

Massoth ® , LGB ® , Lenz ® , Zimo ® , Esu ® , Uhlenbrock ® are registered trademarks of the respective company. 

5.2.7. Switch Decoder Programming 

For programming connect your switch decoder to the programming track and insert the necessary wire bridges 

or unlock the programming lock (e.g. with DiMAX Motor/Switch Decoders) as described in your switch decoder 

manual. One switch needs to be connected as load to the decoder otherwise there is no feedback to the Navigator. 

Enter the main menu with key M3 

and select decoder programming. Select the menu CV programming (older LGB ® decoders need to be programmed 

with register programming) Enter CV number as “1” thereafter insert the value of the desired address 

of your switch decoder. As an example: Programming the address as “20” defines address 17 = first output, 18 

= second output, 19 = third output, and 20 = fourth output. 

5.3. Programming Automatic Functions (Needs software version V1.30) 

This menu contains programming for turnout routes, consists, automated loco operation, and automated switch 

operation. 


MASSOTH 

5.3.1. Turnout Route Programming 

The system allows configuring up to 16 turnout routes containing 15 elements (switches) each. First, define the 

number of the route and confirm with M2 . The window displays element “1” and the cursor jumps to the address 

line requesting an address to be inserted. After inserting the address you choose the switching direction 

with the two arrow keys 

. Confirm your selection with 

M2 . The indication changes to element “2” asking for a new address and operating direction to be inserted. 

Once you’re done configuring elements press M3 and the Navigator recognizes this as the end of the turnout 

route configuration and returns to the normal driving operation. The turnout route is configured and can be 

operated. 

In case you want to edit or shorten a turnout route OK all altered elements with M2 and leave the menu with 

M3 at the point where the elements start that need to be deleted. To delete a single element in a defined turnout 

route is not possible. 

5.3.2. Programming Consists 

The system allows configuring up to 16 consists containing up to 4 locomotives each. First, define the number 

of your consist; this number will be treated like an address. Insert the addresses of the participating locomotives 

and confirm each address with key M2 . Push the M3 key to exit the consist programming menu. The cursor 

always shows the last loco of the consist, hitting M3 ends the consist programming menu and you return to the 

main driving operation. 

5.3.3. Automatic Operation (Automatic Drive) (Needs software version V1.30) 

Note: Beginning with software version V1.40 all contacts in automatic drive and automatic switch will 

be displayed as: 

--> = a /

MASSOTH 

DiMAX transducer). Let us explain the assembly of a shuttle operation: at each location on the track where a 

locomotive is supposed to stop, a reed contact must be installed. Take into calculation the stopping distance of 

the locomotive. Mount the magnet under the gearbox of the locomotive which is supposed to trigger the 

automatic action. Connect the contacts according to the wire diagram of the feedback module. 

The 5 steps of programming are: 

• Consecutive numbers from 1 to 16 

• Define the contact numbers, up to 2048 contacts with 2 trigger directions each. (former “-->” 

corresponds to contact 1a, former “ or

MASSOTH 

This is an example of an automatic drive operation: 

Example of an automatic drive operation 

More explicit instructions concerning automatic drive and automatic switch can be found on our home page 

www.massoth.com/support/documentation . 

5.3.4. Automatic Turnout Operation (Automatic Switch) (Needs software version V1.30) 

The automatic function triggers switch operations by a locomotive. The following components are needed for 

this operation: reed contacts in the track (e.g. LGB ® 17100), triggering magnets to be mounted underneath the 

locomotive (e.g. LGB ® 17010) and a feedback module (280R or LGB ® 55070 via DiMAX transducer). And for 

the switches one switch decoder (LGB ® 55024) for each switch. At each location on the track where an automatic 

switch action is to take place a reed contact must be installed. The reed contact must be positioned in a 

good distance in front of the switch taking into account the train speed and the switch operation time. Mount the 

loco magnet underneath the respective locomotive and install the switch decoder according to the manual. 

Connect the contacts according to the wiring diagram of the feedback module. 

For programming there are 4 steps necessary: 


MASSOTH 

• Consecutive numbers from 1 to 16 

• Define the contact numbers, up to 2048 contacts with 2 trigger directions each. (former “-->” 

corresponds to contact 1a, former “ or

MASSOTH 

5.4. Navigator Configuration 

The Navigator configuration includes backlight control, definition of the emergency mode, language selection, 

programming of the ID number of your Navigator, manual programming of the ID number, blocking alterations 

of the setting of your Navigator, as well as reset to the factory setting. 

5.4.1 Backlight (Dimming feature needs software version V1.50) 

Switch the light of your DiMAX Navigator. Following settings are available with M2 key: 

0 = Lights off 

1 = LCD Display and dial knob illuminated. 

2 = + Keypad illuminated (if new hardware) 

3 = Lights are 50% dimmed 

The red zero point marking light is always illuminated and can not be switched off. We recommend to switch off 

or dim the backlight during wireless operation if your ambient light is sufficient. This extends the endurance of 

the Navigator during wireless operation. 

5.4.2. Emergency Stop Mode 

Choose your preferred key assignment depending on if you are left or right handed. With LEFT and 

RIGHT you define the key which initiates the emergency stop. The emergency stop switches off the track 

power. The second stop key cancels the emergency stop. The option RESET allows sending a HALT 

command. All locomotives are stopped the track voltage however will not be switched off. 

NOTE: 

If you choose the option RIGHT the Emergency Stop is triggered by the right hand stop key. During the 

emergency stop both stop keys of the Navigator are blinking in red alternately. The track power is switched off 

and the emergency stop is cancelled with the left hand stop key. When the emergency stop is cancelled the 

track power is being switched on again and all locomotives that moved during the emergency stop start driving 

again. If you choose RIGHT+RESET you may choose how to halt the locomotives on your layout. The right 

hand key will trigger a regular emergency stop which can be cancelled with the left hand key as explained 

before. The left hand key, however, sends a HALT command to all locomotives running. All locomotives will 


MASSOTH 

come to a stop, the track power, however, will still be on. During the RESET both stop keys are permanently 

illuminated. To cancel the RESET please hit the left hand key again. 

At all times on top of a triggered RESET condition you may initiate an emergency stop. 

NOTE: Some older decoders may not react to the RESET command. In this case the decoder will not switch 

off. 

5.4.3. Language Selection (Update needs software version V1.50) 

Selection of this menu item toggles the Navigator display to another language. The language depends on the 

language file loaded via Software-Update (Chapter 7). Language files are available at our homepage www.massoth.com. 

There are two kinds of language files: 

400H-xx1.dimax = Main language file 

400H-xx2.dimax = Second language file 

Assemble your individual language package on your DiMAX Navigator yourself. 

5.4.4. Programming ID Number 

In tethered operation, the ID numbers of bus components are assigned automatically. This automatic process 

guarantees that no ID number is used twice, thus eliminating the potential for data collisions between devices. 

(If two network devices share the same ID number, collisions may occur during data polling, resulting in erratic 

operation. A collision is when two or more network devices transmit data simultaneously.) 

In tethered operation, ID numbers may also be assigned manually. Please be aware that entering an ID number 

that is shared with another device may adversely impact communication with the central station. 

For wireless operation the IDs must be assigned manually. The IDs for tethered operation and wireless 

operation are independent of each other and each may be entered in this menu. After entering the ID numbers, 

confirm by pressing the M2 key. The Navigator will automatically restart. 

5.4.5. Blocking Functions (Needs software version V1.40) 

The blocking function allows the user to safeguard or lock settings on the Navigator, preventing inadvertent 

changes. To activate the blocking function, place the cursor on the “code:” line and insert the four-digit code of 

your choice. Before confirming the code by pressing the M2 key, write the code number in a secure 

place. Upon pressing the M2 key, the Navigator will return to the normal driving menu, however, only the following 

limited functions will be available: 

• Round dial knob (throttle) 

• Key M1 (unlock the Navigator by re-entering the code) 

• Key pad 1-9 


MASSOTH 

• F-keys 

To deactivate the blocking function, press the M1 key and insert the four-digit code. The code will appear 

below the division line between the primary and the secondary function. After entering the code, press the M1 

key again for confirmation. A checkmark will be displayed behind the code indicating the cancellation of the 

blocking function. 

NOTE: In the event the blocking code is forgotten or misplaced, please email Massoth customer service at 

usa@massoth.com. Please include the serial number of the Navigator. Once we have received the email 

with the Navigator serial number, we will send the release code via return email. 

The serial number is briefly displayed during start-up of the Navigator. When operating in tethered mode, 

press and hold the F-key to extend the display period of the start-up screen. The Navigator serial number and 

software version will be displayed in the lower left corner of the start-up window. In this example, the serial 

number is “50014” and the software version is “V1.40”. The serial number is also printed on a sticker in the 

battery compartment. 

5.4.6. Return Navigator to Factory Default Settings (Needs software version V1.21) 

To access this menu first choose “More” with the M2 key then select “factory settings” 

PRESS THE M2 KEY IF ONLY AND ONLY IF YOU ARE ABSOLUTELY SURE THAT YOU WANT TO 

RESET YOUR NAVIGATOR TO THE FACTORY DEFAULT SETTINGS. OTHERWISE, LEAVE THIS MENU 

BY PRESSING M3 . 

If you reset your DiMAX Navigator, all previously entered data and configurations will be deleted. All configured 

locos, turnout routes, locomotive consists, and switches have to be reprogrammed. After selecting RESET the 

Navigator will restart. The reset process will requires about 40 seconds. 

5.5. Transmitter (Needs software version V1.20) 

5.5.1. Transmitter Installation 

The DiMAX Navigator is available for sale as a tethered unit or as a combined tethered/wireless unit. The latter 

version includes a factory-equipped wireless transmitter. The tethered Navigator may be retrofitted with a 

wireless transmitter (Item# 8133501). Please note, the retrofit procedure is outlined in the User’s Manual for 

the wireless transmitter. 

Navigator software version V1.2 and above is required for wireless operation. Please perform the required 

software update if retrofitting a Navigator that is operating an earlier software revision. Additional information 

and software updates are available at www.massoth.com. 

The current Navigator operating mode, tethered or wireless, is displayed by an icon in the upper right hand corner 

of the display.

5.5.2. Transmitter Configuration 

Beginning with software version 1.2, the DiMAX transmitter configuration menu (RC Config) is available 

and may be selected. 

5.5.2.1. Channel Selection 

Choose the sub menu “channel “with the M2 key and use the cursor to select one of the four available channels. 

The current operating channel will display a check mark. Accept the selection by pressing the M2 key. If 

a new channel is selected, the Navigator will automatically switch off and restart. The factory preset channel is 

channel #1. In some cases it can be helpful to change the RC channel in order to enhance the range. This 

needs to be tested individually. Please remind, changing the RC channel in the Navigator requires the receivers 

RC channel to be changed as well. For further information please read the receivers manual as well. 

5.5.2.2. Frequency Band Selection (Needs software version V1.30) 

Choose between the American frequency band and the European frequency band. 

NOTE: Choosing the European frequency band selection when an American (US) band transmitter is installed 

will not work. 

5.5.2.3. Turn-Off Time 

To conserve battery life during wireless operation, the DiMAX Navigator switches itself OFF after a defined time 

period of inactivity. The Navigator turn-off time can be changed to reflect operational requirements. 

If the Navigator switches itself OFF, all currently logged on locomotives will be logged off. The same result occurs 

if the wireless connection is interrupted or the wireless receiver is disconnected. 


MASSOTH 

5.5.2.4. Battery Charging Function (Needs software version V1.21) 

Activate the charging function by pressing the M2 button. If the Navigator is operated in tethered mode, the 

Navigator’s rechargeable batteries can be charged. This unique feature eliminates the need to remove rechargeable 

batteries for charging.

12. Glossary 

• Bit 

The word “bit” is the truncated form of the term “binary digit.” A bit is the smallest unit of digital data, 

having a value of either “0” or “1.” Eight bits form one “byte” of digital information. 

• Booster 

A booster amplifies a low power DCC signal, providing additional power to the model railway. Each 

booster supplies a single, isolated ‘power district’ on the layout. 

• Bus / Bus system 

A bus system is the electrical connection or data highway between control components of a DCC 

system. The various bus systems being currently utilized by different manufacturers are typically not 

compatible. For example, the bus system for Massoth components is called the DiMAX bus. The bus 

system for Lenz is XpressNet. The bus system for Digitrax is LocoNet. Each features a separate and 

distinct communication protocol. 

• Byte 

A byte is a unit of computer information consisting of eight bits. The decimal value of a byte varies 

between 0 and 255. 

• Central Station 

The central station is the brain of a digital system. All commands, feedback instructions, etc., are 

processed in the central station. The central station generates the bi-polar DC waveform which is 

subsequently amplified by a DCC booster to power the track bus. The central station communicates 

with DCC components – cabs, wireless receivers, feedback modules, etc - via the bus system 

(DiMAX, LocoNet, XpressNet, etc.). 

• Computer Interface or PC Interface 

A computer interface allows the user to connect a digital system to a computer. Typically, the 

interface is a 9-pin serial connector. With appropriate software, the computer can be used to control 

the model railway. Many advanced digital systems include an integral computer interface. 

• CV – Configuration Variable 

DCC decoders allow the user to program various settings through the use of configuration variables 

or CVs. A CV consists of one byte (eight bits) of information and may have a value between 0 and 

255. 

• CV-Programming, Direct Mode CV Programming, (DM) 

CV settings may be changed by a process called CV programming. Direct Mode Programming is 

typically conducted on an isolated, low power (current-limited) programming track section. 

Programming can be accomplished in bit-by-bit mode (allowing one of the eight bits to be altered) or 

in complete byte mode (allowing the whole byte - all eight bits – to be altered). The DiMAX system 

also allows the user to read the value of CVs.

• DCC 

DCC is an acronym for Digital Command Control. With DCC, a digital signal is transmitted along the 

rails and interpreted by devices (decoders) on the network. With NMRA DCC, the communication 

protocol along the rails is standardized, allowing interoperability between manufacturers. Motorola 

and MTH offer competing Digital Command Control systems that are not compatible with NMRA 

DCC. Since the central station and decoders must communicate with the same language or protocol, 

NMRA DCC is not compatible with the Maerklin (Motorola) or MTH (DCS) Digital Command Control 

systems. 

• Decoder 

A decoder (switch decoder, locomotive decoder) converts the commands of the central station 

into the respective action (e.g. operate a switch, control a motor, control lighting outputs). Locomotive 

decoders receive power and instructions from the bi-polar DCC waveform transmitted along the rails. 

• Digital System 

A digital system is an electronic control system designed to allow independent operation of multiple 

trains on the same track. Commands sent to mobile decoders allow the user to control motor speed 

and direction, as well as, the status of various function outputs for lights, smoke units, uncouplers, etc. 

Each locomotive or device controlled by the digital system requires a decoder that features a unique 

address. NMRA digital systems feature standardized communication protocol along the rails. This 

protocol is not compatible with the signal used by other non-NMRA DCC digital systems, e.g., 

Motorola (Motorola) and MTH (DCS). 

• Digital Address 

In a digital system, each mobile decoder (locomotive decoder, function decoder) or stationary decoder 

(accessory decoder, switch decoder) needs a discrete, individually distinct or unique numerical 

address. The capability of the digital system determines the number of available addresses. Basic 

systems, like LGB ® ’s MTS are limited to 22 locomotive addresses and 128 switch decoder addresses. 

More sophisticated systems, like the Massoth DiMAX, are capable of operating up to 10,239 

locomotive addresses and 2,048 switch decoder addresses. 

• MTS 

MTS is an acronym for Multi-Train System, the digital system of LGB ® . While this system does not 

feature the NMRA Conformance Warrant, it is designed to operate according to NMRA DCC 

standards and recommended practices (RPs). 

• NMRA 

NMRA is an acronym for the National Model Railroad Association. The NMRA sets standards and 

recommended practices for NMRA DCC systems. NMRA DCC features standardized communication 

protocol along the rails, offering interoperability between manufacturers. The standardization and 

interoperability does not extend to devices designed to operate on the bus system. 

• PoM = Programming on the Main, a.k.a. Operations Mode Programming 

Traditional programming methods require moving the affected locomotive to an isolated programming 

track. Programming on the Main or Operations Mode Programming allows the user to program the 

decoders of locomotives still sitting on the main operating track. When using PoM, the user selects 


MASSOTH 

the locomotive address of the decoder he wishes to program. Typically, the locomotive address CVs 

cannot be changed with PoM. Please note some decoders are not compatible with PoM. Massoth 

eMOTION XL/XLS decoders are compatible with PoM. LGB ® 55020, 55021, 55022, 55027 and LGB ® 

onboard decoders are not compatible with PoM. 

• Protocol 

Protocol is a set of conventions governing the formatting of data in an electronic communications 

system. In essence, the system protocol is the communication language spoken between devices on 

an electronic network. 

• Speed Steps 

In order to control the driving speed of the locomotive motor, the central station sends direction and 

speed step commands to the mobile decoder. In simple terms, each speed step equates to a pre-set 

drive voltage for the motor. The drive voltage for each of the decoder’s speed steps can be 

programmed by the user. The higher the number of available speed steps, the greater the resolution 

of motor speed control. NMRA DCC allows the central station to send 14, 28 and 128 speed step 

commands to mobile (locomotive) decoders. Basic decoders (e.g., LGB ® 55020) and central stations 

(e.g., LGB ® 55000, 55005) only support 14 speeds steps. Massoth central stations and decoders 

support 14, 28 and 128 speed steps.
